This invention relates to improvements in mens trousers, and more particularly to a novel trouser construction which will enable adjustment of the Waist portion and at the same time preserve the general appearance of the trousers.

There are times when every man has need for adjustability of the waist portion of his trousers. Even in the case of one Whose waistline does not change appreciably over a period of time, there are timeswhen he would like to adjust the waist portion of his trousers Without substantially disturbing the normal appearance. For example, after eating a particularly large meal, ones Waistline is temporarily expanded and it becomes necessary for maximum comfort to relieve the pressure at the waist. At such times, it is not uncommon for one to loosen the waist portion of his trousers even though it results in an unsightly appearance and may be oiensive to others.

Heretofore mens trousers have commonly been constructed with a straight fly front, with buttons or a slide fastener to close the fly portions, and with a button or other fixed fastening device at the top or waistband end of the fly. While the need for adjustability of the Waist portion of mens trousers has been well recognizedther'e has been no satisfactory fulfillment of that need. Resort has been had to such devices as side 'and back buckles which are far from satisfactory. The necessity of maintaining a neat ily closure, equally balanced on both sides, to give a straight out effect has heretofore precluded the provision of waist adjustablity at the ily.

With the foregoing in mind, Vthe present invention has for its purpose the provision of a trouser construction which will meet the need for easy adjustability of the Waist portion at the fly while preserving the normal front appearance. This result is achieved by specially constructing the front of the trousers and by providing cooperative ily and waist fasteners, as hereinafter described more particularly with reference to the accompanying drawings wherein:

Fig. 1 is a fragmentary, front view of a pair oi' mens trousers constructed according to the invention, with the ily open to show the construction;

Fig. 2 is a similar view with the fly closed and with one adjustment of the waist;

Fig. 3 is an enlarged sectional view taken along line 3-3 of Fig. 2;

Fig. 4 is a view similar to Fig. 2 with a different adjustment of the waist;

Fig. 5 is an enlarged sectional view taken along line 5-5 of Fig. 4; and

4 Claims. (Cl. 2-234) Fig. 6 is a View similar to Fig. 4 showing a modification.

Referring particularly to Fig. l, the trousers illustrated comprise a ily-cut body I, a waist portion 2 and a pair of fly portions 3 and 4. The ily portion v4 is adapted to overlap the fly portion 3, so that the latter is the underlying fly portion.

In accordance with the present invention, 'the side 5 of body I is cut along an oblique line 6, instead of along the usual vertical line indicated in dot and dash representation at l. Thus the side 5 is effectively extended circumferentially by the addition of the wedge-shaped area 8 between Llines yIi and 'I. The waistband 2 is correspondingly extended circumferentially by the addition of the area lIl between lines 6 and'I. The.

other side I0 of the body I is cut in the usual manner.

, The ily closure means preferably is in the form o f a slide fastener comprising elements `II and I2 on the ily portions 3 and 4, respectively. The slide fastener element II is carried by a tape I3 secured to ily portion 3 and lying adjacent to line 6. Preferably the element II terminates at a point' I4 a predetermined distance below the waistband. 'I'he slide fastener element I2 is carried by a tape I5 secured to fly portion 4, the element I2 being disposed for cooperation with element II when the fly is closed. Element I2 preferably terminates at a point I6 below the waistband.

VAs may be clearly seen in Figs. 3 and 4, the securing stitches of tapes I3 and I5 Vare sufficiently spaced from the slide fastener elements to providevfree portions of the tapes adjacent said elements, the free tape portions being distendable and foldable to enable free relative movement of the ily portions during adjustment of the waist portion as hereinafter described.

In further accordance with the invention, provision is made for adjustably securing together the overlapable parts I1 and IB at the Waist portion. Preferably a slide fastener is provided comprising a short track element I9 on part I1 and a slider 20 on part I8 adapted to engage element I9. This is a'known form of slide fastener in which the slider may be locked in any position of adjustment.

Assuming that the fly is closed, as shown in Figs. 2 and 4 the waist portion of the trousers may be adjusted very easily merely by adjusting theposition of slider 20 along element I9. The circumferential extension of the waist portion and the upper part of the body adjacent the fly portion 3, i. e. the addition of portions8 and 9.

enables the adjustment of the waist portion. Fig. 2 shows the adjustment for expansion of the waist portion, while Fig. 4 shows the adjustment for contraction of the waist portion. With the adjustment of Fig. 2, the tapes I3 and I5 are transversely distended, as shown in Fig. 3. With the adjustment of Fig. 4, the tapes I3 and I5 are transversely contracted in a folded condition, as shown in Fig. 5. Thus the tapes serve additionally as a flexible connection between the fly portions 3 and 4, and permit the relative adjustment thereof.

Regardless of the adjustment of the waist portion, the fly is kept closed throughout its entire length, and the general appearance is preserved,

with no gaping or otherwise unsightly appear--V ance. The slide fastener element I9 serves to rigdify the top part of the fly and helps to main- 4 sociated y portion, thus enabling relative movement between the ily portions during the adjustment of the waist portion.

2. A trouser construction having a fly-cut body, a waist portion, a pair of fly portions of equal depth one of which is adapted to overlap the other, the overlapping fly portion being substantially vertical in use to provide a normal front appearance, the upper part of the body adjacent the underlying fly portion, and the adjoining part of the waist portion, being cut along an oblique line at a predetermined acute angle to the vertical so as to provide additional material of downwardly tapering wedge form to permit sub- Y/stantial expansion and contraction of the waist portion, vadjustable fastening means on the overl lapable parts of the waist portion to enable the tain a neat appearance. If desired, this may be supplemented by inserting a stiflening member in the waistband lining.

It will be apparent that size of the added area 8 may be varied to give various ranges of adjustability, within the limits of practicability.

Fig. 6 shows a modification wherein the circumferential extension is only at the upper part of the fly and the adjoining waistband. 1n this instance, the body I is cut vertically along line 1 to point 2I and is then cut obliquely along line 22 to add the area 23. During adjustment, the upper part of the ily portion 4 pivots about point 2|. While such construction enables the desired adjustment of the waist portion, it is not as desirable as the rst form.

Thus it will be seen that the invention is capa- Ible of different forms of physical expression and is not limited to one particular construction.

I claim:

1. A trouser construction having a fly-cut body, a waist portion including overlapable parts, a pair of fly portions of equal depth one of which is adapted to overlap the other, adjustable fastening means on the overlapable parts of the waist portion to enable expansion and contraction of the waist portion, and closure means on said ily portions adapted to preserve the normal front appearance while enabling the adjustment of the waist portion with the fly portions remaining closed, said closure means comprising laterally flexible tapes secured to the respective fly portions and slide fastener means including interengageable elements secured to said tapes, the secured portions of said tapes being spaced from said elements to an extent to provide free portions of the tapes which enable relative move- 5 ment between each fastener element and the asexpansion and contraction of the waist portion, and closure means on said fly portions adapted to preserve the normal front appearance while enabling the adjustment of the waist portion with the ily portions remaining closed, said closure means comprising laterally flexible tapes secured to the respectivel ily portions and slide fastener means including interengageable elements secured to said tapes, the secured portions of said tapes being spaced fromL said relements to an extent to provide lfree. portions of the tapes which enable relative movement between each fastener element and the associated fly portion, thus enabling relative movement between the ily portions during the adjustment of the waist portion.

3. A trouser construction according to claim 2, wherein said additional material is substantially coextensive with the underlying ily portion.

4. A trouser construction according to claim 2, wherein said additional material is limited to the areaadjacent the upper part of the underlying fly portion.
